Thanks.
I would love to be informed if you ever decide to make more.
Topic: Aluminum Casascius Coins [sold out] (Read 4481 times)
Sorry to revive an old thread but I just found out about these coins and since they are no longer being produced I searched on ebay and found this:
http://www.ebay.com/itm/Casascius-10-mBTC-01-Btc-Bitcoin-physical-loaded-Not-Litecoin-FTC-Digital-/171196456193?pt=LH_DefaultDomain_0&hash=item27dc1a9d01
Are these the ones? I don't see the coin number on these like the ones you originally made so I feel like they are knockoffs?
Thanks for any input.

No, those are not mine.

Nice coins!
I'm interested in the next batch. And you should take Casascius up on the colored coins.

Excuse that unpleasant hacker that decided to post negative comments about your coins using my account...I think all physical coins are cool as shit, and yours are no exception. this prick really got around that day pissing on all kinds of threads using my account as his puppet. Discovered it two days later, after a bunch of people decided they didn't like me anymore because my avatar brazenly insulted them, understandable, but it sucks that some people truly believed that was me.
Not a problem hennessyhemp. Sorry you had issues with your account.
I don't remember if I have mentioned this before, but you can use a 29x29 QR code with a Q error-correction level if you store a mini-key. The reduced resolution and higher error correction will make the QR code much more reliable. Here is what one would look like:
Yeah, I actually started out using the minikeys but only the mt.gox app would read them in. None of the other phone wallets would read in the mini keys from a qr code. There was more support for the WIP key. I'm hoping more apps support the minikeys from qr code in the future though. The blockchain.info web app lets you import minikeys by typing them in but when you try to read in a qr code on your phone it gives an error about how mini format not supported or something like that.
I think these coins are pretty good for give aways. Good job OP! 
One question: Is there any risk of the QR code that is put under hologram to rub off accidentally? Has this been tested? Keep in mind I do not have any idea how you are getting them on to the coins as I have no experience/knowledge with that specific type of work.
Edit: One more thing I noticed, how well does the QR code read when printed over the indentation on the back? Have you run into any issues with the translation when being read in?

Hey there smoothie, I missed your questions the first go around. The hologram scratch off has a clear plastic bottom and the qr code is laser printed underneath. So it should be safe with any reasonable amount of pressure. I scratched fairly hard in testing and all worked well. As for reading the QR code, I had no problems at all in testing. That picture of coin #2 on the first post was one of the actual coins tested (not sold obviously). I haven't tried but you can probably read the QR code just from the picture (the key is empty now obviously
This is friggin awesome.
Posting out of commercial interest, since I don't have time to read right now.

Lealana coins does it better.
Lealana coins has not even sent any coins out. There is even a scam accusation against smoothie regarding the ccoins. Stop posting random comments on a lot of threads that you aren't even interested in just to bring your post count higher.
By the way, good for you Casascius for being open and helpful to any new competition. Good to see that in today's market where monopoly's are every company's goal it seems like.
Hey Casascius, I'm actually using some silver foil labels. I originally looked at trying to laser on the coins directly as I have a close friend who does that sort of thing as a business but I ran into the same issues you did.
I would be interested when you get the flat back coins in. The recess sometimes causes me fits when putting a label on without an air pocket

If you'd be interested in the anodized (colored) aluminum ones, the price is a bit higher (like 20 cents more a coin), but if you have access to a laser machine and can script a job for it the same way you did these labels, you might be able to mass produce coins just by laying them on the bed. I have several colors: gold, blue, red, green, purple.
Also I thought you mentioned you were using tweezers to place the labels and that it was slow. Here is another way that has always worked fabulously for me. Go to HomeDepot.com and do a search for "706060" (this is the manufacturer's item number, or search by home depot's SKU 538167). It's brown paper tape meant for painters that is weakly sticky, and only on one edge. I use the sticky edge to pick up a row of labels off a sheet, and the non-sticky portion is large enough to make it easy to hold and position stickers. This might or might not work for scratchoffs if it's too sticky to take the scratch away, but will definitely work with holograms or non-scratch stickers.
Spend more money on the holograms.
For being a candidate for a cheap low cost proof of concept "tip jar" coin, I think they look pretty darn good.
Sure yeah, spend $5000 on custom holograms. Pad that cost into the price. Then you'll end up with a coin that cost too much you won't want to give away, defeating the whole purpose of a low cost coin.
EDIT: simply to add this acknowledgment that I responded to a hacker
Your holograms look horrible, sorry.
haha thanks for your input? You just made my night.
Very cool! Very impressed!
How are you printing on these? Are you lasering them? Transparent labels?
I own an Epilog Mini laser machine I use for my other stuff. It's an infrared CO2 laser. This laser won't do squat to the aluminum coins, the beam just reflects off with no effect - unless I pre-coat the coins with something like CerMark spray, which is a bit expensive (not to mention messy), but makes the mark a nice solid black sort of how yours look. Are you doing something similar, or perhaps have a different type of equipment that can mark bare metal?
I also have colored anodized aluminum coins. The laser will burn off the coloring and leave nice silver-white lettering behind, but I haven't gotten around to developing software to feed unique private keys to the laser machine quite yet. And the anodized aluminum coins cost a fair bit more than the bare ones.
Also I have more of the aluminum coins on the way with flat backs (no recess) and I will be shipping them out by default in future orders after they arrive.

Would you be able to make 10 of these coins each with .1 on them instead of .01? and print 100 mBTC on them and such. If so what would be your shipped price for the lot?
Hey KingofSports, I answered you in pm but I'll put this out here too.
The next set will be done as soon as I get back home (next week sometime). They will be 0.05 btc (50 mBTC) denomination and there will be 48 of them total like the first set. I'll make a new post when they are finished.
I will take 10 please, same shipping info as before.
Let me know when you are ready to open purchasing.

Been a little busy lately but I wanted to reply,
Serp is great to work with, very professional and fast shipping.
I ordered them via PM on June 26th, They shipped out on the 27th via USPS first class mail delivered on July 1st.
The coins themselves are light as is to be expected for being aluminum and all but overall they are very nice.
Congrats serp, keep up the good work, please let me know when you have more in stock, I will be buying more for my twin 10 year olds.
If anybody wants pics, let me know and I will post some on this thread.
Happy Friday!
